As of early 2026, there is no general "can ban" on the Guadalupe River in the unincorporated areas of Comal County, which is where the majority of tubing takes place. Unlike the neighboring Comal River in New Braunfels, which has a strict "no disposable container" ordinance, the Guadalupe allows you to bring aluminum cans and plastic bottles. However, there are still strict regulations to follow: glass and Styrofoam are prohibited on the water, and you must adhere to "volume" rules regarding jello shots (containers 5oz or less are banned). In 2026, authorities continue to enforce "anti-littering" laws and may issue heavy fines for anyone seen throwing trash into the river. Additionally, if your tubing trip starts or ends within the New Braunfels city limits, you must be aware of the "Can Ban" that applies there. It is highly recommended to use a mesh bag tied to your tube for all empties. While the Guadalupe remains a "party-friendly" river where you can enjoy beverages in cans, the "Respect the River" campaigns have become more prominent to ensure the natural beauty of the Texas Hill Country is preserved.
